TO ALL WHOMLQIT MAY CONGEBN:

Be it known that we, JAMES A. NIMAN and BENJMIN FIDLER', of Mansfield, in the county of Richland, and State of Ohio, have invented a new and useful improvement in a Machine for Bending Tire for Wheels, Sto.; and we do hereby declare that. the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of thsspecificaton, in which- Figure l is a side elevation.

FigureQ, a longitudinal section.

Figure 3, an end view.

Figure 4, a plan; and

Figure 5, the elevation of the right and left-hand screw, rollercarriages and rollers, as seen when detached from the rest of the machine.

In this machine, A is the xed central roller; B, the traversing and working-rollers; C, the frame and bed of the machine; F, the carriages which carry the rollers-B, which said carriages slide freely on and in the frame C; I is a right and left-hand screw, running through and tapped or screwed into the roller-carriages F,

and which said screw is provided with a fast collar, H, which works freely in a recess'tted for the purpose in the bed of the machine; is the handle to turn'the screw, and Fr are the handles for turning therollers B.

In operation, the rollers B areset at .the required distance from the central roller A, to bend the iron to the required circle, by means of the right and left-hand screw, worked by the handle D, which slide the carriages F, which carry the rollers B nearer to or further from the central roller A the distance required. After the insertion of the iron into the rollers it is bent in the usual manner by turning the rollers B by means of their handles E. I

I i Claim.

In this machine, we do not claim the frame C, or the rollers marked A and B, neither do we claim the handles E, all of which are now in use and well known; but what we do claim as our invention and improyement, and desire to secure by .Letters Patent, is A The right and left-hand screw I, provided with a collar, H, working in a recess in the bed of the machine, combined with the sliding or traversing-roller carriages F, which carry the rollers B, which said screw is tapped or screwed into and through the saidA roller-carriages F, and by means of which said combination we are enabled i to set the rollers B eqidistant nearer to or -further from the central roller A for the purpose required, and Y retain them in place, all of which is substantially set forth, described, and shown in the accompanying drawings,

and in this specification.
